Yesterday I opened a new bag of Winchester brass to find five cases (out of fifty) that are not usable. These five pieces of brass have deep cuts in the shoulder area. One piece has the cut entirely through the brass. The forty five other cases are in great shape.

I have been loading for many years and I expect dents in bagged brass. This is the first time I have ever seen cut marks. If I had loaded these cases they certainly would have split upon firing.
